Which type of cells are capable of engulfing bacterial cells?

White blood cells, specifically a class known as phagocytes, are responsible for engulfing and destroying bacterial cells. This process is part of the body’s immune response to infection. White blood cells, such as neutrophils and macrophages, identify pathogens through various signals and then surround and ingest these harmful invaders in a procedure known as phagocytosis. Once engulfed, the bacteria are broken down and eliminated, preventing the spread of infection.

In contrast, red blood cells primarily function to transport oxygen and carbon dioxide between the lungs and tissues and do not have a role in engulfing pathogens. Platelets are involved in blood clotting and do not possess the ability to phagocytize bacteria. Neurons, the cells of the nervous system, are specialized for communication and do not participate in immune responses. Hence, white blood cells are uniquely equipped and designed to combat bacterial infections through their phagocytic abilities.
